A key driver for Welsh Water in its selection of partners for AMP6 was to identify companies who could work collaboratively in the new Capital Delivery Alliance.

The Alliance is designed to drive value in the planning and pre-construction phase by co-locating Welsh Water, contractor and consultant resource into a single Integrated Solutions Team to “help facilitate collaboration and innovation.”

Chris Jones, Welsh Water’s Chief Executive, said: “As a company, we want to deliver the best possible outcomes for our customers and for the environment at the most affordable price.

“We went through an extensive procurement process to ensure that we selected capital partners that share our vision and values and are committed to delivering the customer service, environmental and financial outcomes that our customers want and deserve.”
